Raman-Accelerated Power Depletion of Fundamental Mode in a Few-Mode Fiber in the Visible Spectral Range
Wasyhun A. Gemechu, Guohao Fu, Mario Zitelli
We experimentally and numerically investigate Raman-driven power depletion in the fundamental mode of few-mode fibers (FMFs) excited by visible ultrashort pulses. Using a tunable f…

Light tailored by multimode fiber for multiphoton fluorescence microscopy
Raphael Jauberteau, Alessandro Tonello, Yifan Sun +8
We study the diffraction of a particular class of beams, composed only by a combination of azimuthally invariant guided modes of an optical fiber. We demonstrate that such beams ca…
